- The meteor that killed the dinosaurs ( I forget its name, I can't remember everything) was so devastating because of the total condition of the Earth and where the meteor hit. There was 10 % more oxygen in the atmosphere so the air was more combustible. Also, the meteor hit water about ten meters deep with a layer of sulfur underneath. The sulfur was thrown up into the air and the water instantaneously evaporated, creating acid rain that could burn the flesh off of creatures. 95% percent of the species on Earth were wiped out. That's the species, not of total life. For that the count goes higher. At least I think I have that right. Source is Bill Bryson.

- The amount of pain a person feels and their overall condition when gunshot is highly dependent upon the situation in which they were shot. Soldiers tend to not need as much morphine or medical care and the theory is they have more to look forward to. They get to leave combat, go home, be treated like a hero, etc. People shot randomly have much less to look forward to: lost work time, medical bills, possible death, etc. This leads people randomly shot close to home to beg for drugs to numb physical and emotional pain. Of course all this is null and void if the gunshot is fatal, no matter who the victim be. Source: radio lab.
